我校是为招收本地区七县一市边远贫困山区少数民族农家子弟入学而于1992年新开办的一所民族中学,在校生中有彝、苗、回、仡佬、布依等十多个少数民族.为了提高教学质量,学校决定在97届初中生的数学教学中使用《GX 初中数学实验教材》,通过三个学期的教学实践,我们拟就《二次根式》一章的教学,谈谈对 GX 教材的一些看法,以作引玉之砖.《二次根式》一章的基础是与根式有关的性质和公式,重点是二次根式的运算与化简.对这一章的处理,现行教材分两点:一、先讲“数”后
Our school is a minority high school newly established in 1992 to enroll students from ethnic minority farms in remote and impoverished mountainous areas in seven counties and one city in the region. Among the students, there are more than a dozen ethnic minorities such as Yi, Miao, Hui, Dai, and Buyi. In order to improve the teaching quality, the school decided to use the “GX junior high school mathematics experiment teaching material” in the 97 junior high school students’ mathematics teaching. Through three semesters of teaching practice, we plan to teach the teaching of the “secondary root style” chapter. Some of the views of the GX textbooks are used as a reference to the jade brick. The basis of the chapter “Secondary Roots” is the nature and formula related to the root formula. The emphasis is on the calculation and simplification of the secondary roots. The treatment of this chapter, the current There are two points in the textbook: First, after the “number”
